Christians and non-Christians

Beautiful Travel Pic, Twitter, China, colourized

LANGER, SUSANNE K (1953)(1967) An Introduction to Symbolic Logic, Dover Publications, New York.

The Langer philosophy text review, continues.

Some key symbols from the textbook:
≡df = Equivalence by definition
: = Equal (s)
ε = Epsilon and means is
⊃ = Is the same as
⊨ is Entails
˜ = Not
∃ = There exists
∃! = There exists
∴ = Therefore
· = Therefore
= Is included
v = a logical inclusive disjunction (disjunction is the relationship between two distinct alternatives).
x = variable

Two complementary classes not only divide the universe between them (universe of discourse, my add), but they are mutually exclusive. (145).

Christians and non-Christians would divide a universe of discourse. (My add).

Christians = A
Non-Christians= -A

This philosophically would encompass the entirety of humanity as a universe of discourse.

Christians = A
Non-Christians= -A

One form is a denial of the other. (145). As consequence, no element in the universe can be true of both forms, and no individual can be of both classes. (145).

Taking this concept to biblical studies and theology:

Christians = A

Non-Christians= -A

Example:

A

Mathew 28: 18-20: New Testament, disciples.

-A

Mathew 28: 18-20: New Testament, non-disciples.

Please see comments section for more examples.

Langer writes that this is a negative statement:

(∃x) : ˜ (x ε A) (145).

x Exists does not equal x is A.

or

x does not equal x is A.

This is in a positive form:

(∃x) : x ε -A (145).

x Exists equals x is not A.

or

x equals x is not A.

What is reasonable?

Vancouver: Today

What is reasonable?

BLACKBURN, SIMON (1996) Oxford Dictionary of Philosophy, Oxford, Oxford University Press.

I viewed Tucker Carlson Tonight, last night and posted on his Twitter page a reply to his request to know what is reasonable (thought).

@TuckerCarlson Blackburn: Paraphrase-To accept something as rational is to accept it as making sense, as appropriate, aiming at truth. (319)

Replying to @RNMPhD @TuckerCarlson The prof. you debated needs to use texts. (Blackburn, Oxford Dictionary of Philosophy)

Replying to @RNMPhD @TuckerCarlson Blackburn: Reasoning is any process drawing a conclusion from premises. Under reason Blackburn states see rationality. (Being reasonable)
---

On Twitter I am limited to 140 character tweets. So, obviously, an even more limited presentation than on Blogger.

The professor, Mr. Carlson was debating stated (paraphrased) that reasonable thought and arguments were what the average person would use and state. I suppose she meant what is considered reasonable by the average person. Within various worldviews the average person can believe things not rational/reasonable. A society, in general can accept premises and arguments not rational/reasonable. This criteria lacks objectivity.

To continue with Blackburn's definition: Rationality from 319/Reason 320:

To accept something as making sense, appropriate, required, in accordance with some acknowledged goal, as in the truth, or the good. (319).

I would define reason and rationality as:

Rationality and reason are the use of true premises and true conclusions.

This is non-exhaustive but philosophically acceptable.

Prove to me, I am not the most handsome man ever to exist!

Majorca, Spain, Facebook (Would be nice today).

PIRIE, MADSEN (2006)(2015) How To Win Every Argument, Bloomsbury, London.

Prove to me, I am not the most handsome man ever to exist!

April 18

The argumentation ad ignorantiam is committed when the lack of knowledge is presented to infer that the opposite is true. (126).

Pirie opines that shifting the burden of proof is a specialized form of argumentation ad ignorantiam, asserting a premise without justification. (187). The audience must disprove of the premise for it to be rejected. (187).

'Give me a good reason this is not true'.

This is an example based on what was presented by the author. But, it is the assertion, the premise that needs to be justified in an argument, not the resistance to it, or the arguments against it. (187). It is assumed that something is acceptable unless proven otherwise. (187).

Prove to me I not the most handsome man ever to exist!

(Yes, this is fallacious. My photos are a clue this is a questionable proposition. I am somewhere between pretty boy and tank on the looks scale)

Pirie explains this fallacy fuels belief in UFOs, monsters, demons, etcetera. (188).

On the point of demons, I differ:

I acknowledge that demonic belief can be presented with fallacious premises.

But a reasonable theological belief in Satan and demons is based in scriptural, documented, history, not in premises of lack of knowledge. I do not focus on 'prove to me, it is not true' premises in regard to the supernatural. Demonic belief is primarily based on scripture, even for those of us that reason we have seen and heard demonic activity in humanity.

FOF

I listen to Focus on the Family (FOF), 'Boundless' occasionally. Here are reasoned premises based on listening. The Focus on the Family American (Canadian), philosophy of dating.

Non-exhaustive and not in every case.

He reads his Bible.
He leads at church.
He has Christian maturity.
He has good employment.
He is attractive.
He is relatable.
He is within five years of age.

Therefore, he is a potential date.

He reads his Bible.
He leads at church.
He has Christian maturity.
He has good employment.
He is attractive.
He is relatable.
He is ten years plus older.

Therefore, he is a potential acquaintance.

He has secular views.
He attends church.
He has Christian background.
He has good employment.
He is attractive.
He is relatable.
He is within five years of age.

Therefore, he is a potential date.

My suggested

He reads his Bible.
He leads at church.
He has Christian maturity.
He has good employment.
He is attractive.
He is relatable.
He is youthful.

Therefore, he is a potential date.

If my evaluation of FOF views are reasonably correct, a reason why many young women reject attractive older men is because age difference is more important than Christian walk. The generally greater physical attraction of younger men and social rules are more important than spiritual maturity when comparing younger men to older men.

Are we on shifting ground?

The Pirie entry by entry review continues...

PIRIE, MADSEN (2006)(2015) How To Win Every Argument, Bloomsbury, London.

The Definitional Retreat

'A definitional retreat takes place when someone changes the meaning of the words in order to deal with an objection raised against the original wording. By changing the meaning, he turns it into a different statement.' Pirie uses an example: 'When I said I hadn't been drinking, officer, I meant that I hadn't had more than I get through in a normal social evening.' (77-78). 

My examples: 

When I said I was a Christian, I meant that I think there is probably a God. 

When I said you were fat, I meant that you were phat, as in excellent. 

The author explains that a definitional retreat allows a person to save face when their argument has been demonstrated to significantly lack merit. (78). Pirie reasons that philosophers often change definitions when shown as questionable. (78). Definitions are not to be subjective, they have objective meanings. This is a reason I revise my writing, because sometimes corrections have to be made in premises, conclusions and reasoning. 

Definition twisting, does not assist with my pursuit of the truth. My revisions are documented when significant. I admit that minor revisions are often made after publish, because some problems are not apparent until after publish. That is a visual issue, not an integrity one. But if I do change my mind...it is better to revise statements and/or arguments when needed and to note it. 

Pirie mentions that UK finance ministers are good at the use of this fallacy. (79). They use definitional retreat. I think politicians often use fallacies when definitions are changed to portray a different story. Statistics can be stated to mean one thing in January and something else in December. 

Shifting ground?

When making arguments, people may hedge with ambiguous premises. (185). Or people may use a definitional retreat to make words within premises mean something else. (185). A type of this defensive type of argumentation is to use shifting ground. (185). This fallacy is used with attempts to avoid criticism of an original premise (s) by shifting the meaning of premise or premises. (185). This would require a new critique of the argument. (185).

My examples:

Premise: I think x is a bad thing.

Conclusion: Yes, x should be banned.

After negative critique from others, the shifting ground fallacy is used:

Premise: Rather, x is usually a bad thing.

Conclusion: Well, x should probably be banned, anyway.

As Pirie explains the arguer will change the ground he/her is standing on and still maintain the continuity of the argument. (185). It is fallacious to change the substance of what is being stated.

In my example, the premise shifts from 'is a bad thing', to 'is usually a bad thing'.

The conclusion shifts from 'should be banned' to 'should probably be banned, anyway'.

Based on my years of discussion and debating, this is a tempting fallacy for intellectual and non-intellectuals, alike, to use as defence. As with my writing on my websites, sometimes arguments simply require edits in humility. The person in my example is attempting to save face, when he/she should more likely reconsider the entire line of reasoning.

Pirie opines that politicians at times use the shifting ground fallacy rather than admit that he/she changed their mind. (186). The shifting ground fallacy is often used when one cannot prove his/her point but does not want to appear to be wrong, or admit he/she is wrong. (186).

Hedging


'Hedging in arguments means sheltering behind ambiguous meanings so that the sense can be changed later.' (120). To paraphrase the author's example: We stated we did not want a full-fledged war in the Middle East; that is still the position, we entered into limited war. (120). This type of argumentation allows for a 'definitional retreat.' (120). 'Hedging is fallacious because it puts two or more different statements under the guise of one'. (120). It is a semantic game in parsing the difference between a 'limited war' and a 'full-fledged' war. Is any war 'full-fledged' without nuclear weapons? Hedging hopes that the reviewer of argumentation, will not know better (120); the information presented becomes useless because it is not presented accurately. (120). To avoid hedging one could state: 'We are entering into war; we are committed.' Or: 'We are not entering into war, because the risks are too great.' Hedging again... We stated we did not want to colonize Mars, that is still the position, but we have several Mars space missions planned. 

Interestingly, Pirie indicates that Nostradamus used hedging to make obscure predictions. (121). The author reasons that observers look for what they want to see as far as what has already occurred and apply what Nostradamus predicted. This does not assist in making accurate predictions. (121). Hedging uses dishonesty and ambiguity. (121).
